Bitter melon extract (BME) inhibits ovarian cancer cell migration and invasion. (A) Wound healing assays demonstrating that there was a marked retardation in wound closure rate of SKOV3 cells treated with 5% and 10% (v/v) Chinese BME compared with untreated controls over a time course of 12 hours (*P ≤ .001). The width of the wound is indicated by arrows in the photographs; 3 independent experiments were performed. (B) Transwell migration assay showed that SKOV3 cells with Chinese BME treatment (5% and 10%) exhibited a significant reduction in the number of cells penetrating through the membrane as compared with untreated controls (*P ≤ .001). (C) SKOV3 cells treated with Chinese BME (10%) showed less invaded cells through the matrigel as compared with the control (*P = .0006). The numbers of migrated or invaded cells in 3 randomly chosen fields were counted for 3 independent experiments, and the normalized numerical data were presented in bar charts with error bars.
